While talking with a friend in Denmark, he advised me that Hagar (as in Hagar the Horrible) is pronounced "Hog-Arrgh." As Hagar existed prior to the existence of rail-roads, any chantey written about him would have to predate the Hogeye song.

The chorus and a couple of verses go:

And it's Hagar, Big old viking name of Hagar, Charge ashore with his broadsword, Oh, He is the Hagar man.

Helga is old Hagar's wife, She's why he chose the viking life.

Hagar has invaded France So he and Helga can learn to dance.

Hagar's ship has a viking crew If you get too close they'll shanghai you!

Clearly, this song has old and new elements but I am sure some you of you 'know' verses I have not yet included in the song.
